public static void main(String[] args) {
int[] a = {1,2,3,23,56,45,88};
int[] b = {3,2,3,23,56,45,88};
double[] c = new double[a.length];
for(int i = 0;iif(b[i] == 0){
return;
}
double s = (double)a[i]/b[i];
// DecimalFormat df = new DecimalFormat("#.00");
// System.out.println(df.format(s));
// c[i] = Double.valueOf(df.format(s));
// System.out.println(c[i]);
NumberFormat nf = NumberFormat.getNumberInstance();
nf.setMaximumFractionDigits(2);
System.out.println(nf.format(s));
c[i] = Double.parseDouble(nf.format(s));
}
}
int[] a = {1,2,3,23,56,45,88};
int[] b = {3,2,3,23,56,45,88};
double[] c = new double[a.length];
for(int i = 0;iif(b[i] == 0){

NumberFormat nf = NumberFormat.getNumberInstance();
nf.setMaximumFractionDigits(2);
System.out.println(nf.format(s));
c[i] = Double.parseDouble(nf.format(s));
}
}
